9 Warren, Henry Ellis
SUBJECT AREA: Horology[br]b. 21 May 1872 Boston, Massachusetts, USAd. 21 September 1957 Ashland, Massachusetts, USA[br]American electrical engineer who invented the mains electric synchronous clock.[br]Warren studied electrical engineering at the Boston Institute of Technology (later to become the Massachusetts Institute of Technology) and graduated in 1894. In 1912 he formed the Warren Electric Clock Company to make a battery-powered clock that he had patented a few years earlier. The name was changed to the Warren Telechron (time at a distance) Company after he had started to produce synchronous clocks.In 1840 Charles Wheatstone had produced an electric master clock that produced an alternating current with a frequency of one cycle per second and which was used to drive slave dials. This system was not successful, but when Ferranti introduced the first alternating current power generator at Deptford in 1895 Hope-Jones saw in it a means of distributing time. This did not materialize immediately because the power generators did not control the frequency of the current with sufficient accuracy, and a reliable motor whose speed was related to this frequency was not available. In 1916 Warren solved both problems: he produced a reliable self-starting synchronous electric motor and he also made a master clock which could be used at the power station to control accurately the frequency of the supply. Initially the power-generating companies were reluctant to support the synchronous clock because it imposed a liability to control the frequency of the supply and the gain was likely to be small because it was very frugal in its use of power. However, with the advent of the grid system, when several generators were connected together, it became imperative to control the frequency; it was realized that although the power consumption of individual clocks was small, collectively it could be significant as they ran continuously. By the end of the 1930s more than half the clocks sold in the USA were of the synchronous type. The Warren synchronous clock was introduced into Great Britain in 1927, following the setting up of a grid system by the Electricity Commission.[br]Principal Honours and DistinctionsFranklin Institute John Price Wetherill Medal.

10 Ferranti, Sebastian Ziani de
[br]b. 9 April 1864 Liverpool, Englandd. 13 January 1930 Zurich, Switzerland[br]English manufacturing engineer and inventor, a pioneer and early advocate of high-voltage alternating-current electric-power systems.[br]Ferranti, who had taken an interest in electrical and mechanical devices from an early age, was educated at St Augustine's College in Ramsgate and for a short time attended evening classes at University College, London. Rather than pursue an academic career, Ferranti, who had intense practical interests, found employment in 1881 with the Siemens Company (see Werner von Siemens) in their experimental department. There he had the opportunity to superintend the installation of electric-lighting plants in various parts of the country. Becoming acquainted with Alfred Thomson, an engineer, Ferranti entered into a short-lived partnership with him to manufacture the Ferranti alternator. This generator, with a unique zig-zag armature, had an efficiency exceeding that of all its rivals. Finding that Sir William Thomson had invented a similar machine, Ferranti formed a company with him to combine the inventions and produce the Ferranti- Thomson machine. For this the Hammond Electric Light and Power Company obtained the sole selling rights.In 1885 the Grosvenor Gallery Electricity Supply Corporation was having serious problems with its Gaulard and Gibbs series distribution system. Ferranti, when consulted, reviewed the design and recommended transformers connected across constant-potential mains. In the following year, at the age of 22, he was appointed Engineer to the company and introduced the pattern of electricity supply that was eventually adopted universally. Ambitious plans by Ferranti for London envisaged the location of a generating station of unprecedented size at Deptford, about eight miles (13 km) from the city, a departure from the previous practice of placing stations within the area to be supplied. For this venture the London Electricity Supply Corporation was formed. Ferranti's bold decision to bring the supply from Deptford at the hitherto unheard-of pressure of 10,000 volts required him to design suitable cables, transformers and generators. Ferranti planned generators with 10,000 hp (7,460 kW)engines, but these were abandoned at an advanced stage of construction. Financial difficulties were caused in part when a Board of Trade enquiry in 1889 reduced the area that the company was able to supply. In spite of this adverse situation the enterprise continued on a reduced scale. Leaving the London Electricity Supply Corporation in 1892, Ferranti again started his own business, manufacturing electrical plant. He conceived the use of wax-impregnated paper-insulated cables for high voltages, which formed a landmark in the history of cable development. This method of flexible-cable manufacture was used almost exclusively until synthetic materials became available. In 1892 Ferranti obtained a patent which set out the advantages to be gained by adopting sector-shaped conductors in multi-core cables. This was to be fundamental to the future design and development of such cables.A total of 176 patents were taken out by S.Z. de Ferranti. His varied and numerous inventions included a successful mercury-motor energy meter and improvements to textile-yarn produc-tion. A transmission-line phenomenon where the open-circuit voltage at the receiving end of a long line is greater than the sending voltage was named the Ferranti Effect after him.[br]Principal Honours and DistinctionsFRS 1927.

11 Edison, Thomas Alva
SUBJECT AREA: Architecture and building, Automotive engineering, Electricity, Electronics and information technology, Metallurgy, Photography, film and optics, Public utilities, Recording, Telecommunications[br]b. 11 February 1847 Milan, Ohio, USAd. 18 October 1931 Glenmont[br]American inventor and pioneer electrical developer.[br]He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.[br]Principal Honours and DistinctionsMember of the American Academy of Sciences.

12 Bulleid, Oliver Vaughan Snell
[br]b. 19 September 1882 Invercargill, New Zealandd. 25 April 1970 Malta[br]New Zealand (naturalized British) locomotive engineer noted for original experimental work in the 1940s and 1950s.[br]Bulleid's father died in 1889 and mother and son returned to the UK from New Zealand; Bulleid himself became a premium apprentice under H.A. Ivatt at Doncaster Works, Great Northern Railway (GNR). After working in France and for the Board of Trade, Bulleid returned to the GNR in 1912 as Personal Assistant to Chief Mechanical Engineer H.N. Gresley. After a break for war service, he returned as Assistant to Gresley on the latter's appointment as Chief Mechanical Engineer of the London \& North Eastern Railway in 1923. He was closely associated with Gresley during the late 1920s and early 1930s.In 1937 Bulleid was appointed Chief Mechanical Engineer of the Southern Railway (SR). Concentration of resources on electrification had left the Southern short of up-to-date steam locomotives, which Bulleid proceeded to provide. His first design, the "Merchant Navy" class 4–6– 2, appeared in 1941 with chain-driven valve gear enclosed in an oil-bath, and other novel features. A powerful "austerity" 0−6−0 appeared in 1942, shorn of all inessentials to meet wartime conditions, and a mixed-traffic 4−6−2 in 1945. All were largely successful.Under Bulleid's supervision, three large, mixed-traffic, electric locomotives were built for the Southern's 660 volt DC system and incorporated flywheel-driven generators to overcome the problem of interruptions in the live rail. Three main-line diesel-electric locomotives were completed after nationalization of the SR in 1948. All were carried on bogies, as was Bulleid's last steam locomotive design for the SR, the "Leader" class 0−6−6−0 originally intended to meet a requirement for a large, passenger tank locomotive. The first was completed after nationalization of the SR, but the project never went beyond trials. Marginally more successful was a double-deck, electric, suburban, multiple-unit train completed in 1949, with alternate high and low compartments to increase train capacity but not length. The main disadvantage was the slow entry and exit by passengers, and the type was not perpetuated, although the prototype train ran in service until 1971.In 1951 Bulleid moved to Coras Iompair Éireann, the Irish national transport undertaking, as Chief Mechanical Engineer. There he initiated a large-scale plan for dieselization of the railway system in 1953, the first such plan in the British Isles. Simultaneously he developed, with limited success, a steam locomotive intended to burn peat briquettes: to burn peat, the only native fuel, had been a long-unfulfilled ambition of railway engineers in Ireland. Bulleid retired in 1958.[br]BibliographyBulleid took out six patents between 1941 and 1956, covering inter alia valve gear, boilers, brake apparatus and wagon underframes.Further ReadingH.A.V.Bulleid, 1977, Bulleid of the Southern, Shepperton: Ian Allan (a good biography written by the subject's son).C.Fryer, 1990, Experiments with Steam, Wellingborough: Patrick Stephens (provides details of the austerity 0–6–0, the "Leader" locomotive and the peat-burning locomotive: see Chs 19, 20 and 21 respectively).PJGRBiographical history of technology > Bulleid, Oliver Vaughan Snell

13 Bacon, Francis Thomas
SUBJECT AREA: Aerospace[br]b. 21 December 1904 Billericay, Englandd. 24 May 1992 Little Shelford, Cambridge, England[br]English mechanical engineer, a pioneer in the modern phase of fuel-cell development.[br]After receiving his education at Eton and Trinity College, Cambridge, Bacon served with C.A. Parsons at Newcastle upon Tyne from 1925 to 1940. From 1946 to 1956 he carried out research on Hydrox fuel cells at Cambridge University and was a consultant on fuel-cell design to a number of organizations throughout the rest of his life.Sir William Grove was the first to observe that when oxygen and hydrogen were supplied to platinum electrodes immersed in sulphuric acid a current was produced in an external circuit, but he did not envisage this as a practical source of electrical energy. In the 1930s Bacon started work to develop a hydrogen-oxygen fuel cell that operated at moderate temperatures and pressures using an alkaline electrolyte. In 1940 he was appointed to a post at King's College, London, and there, with the support of the Admiralty, he started full-time experimental work on fuel cells. His brief was to produce a power source for the propulsion of submarines. The following year he was posted as a temporary experimental officer to the Anti-Submarine Experimental Establishment at Fairlie, Ayrshire, and he remained there until the end of the Second World War.In 1946 he joined the Department of Chemical Engineering at Cambridge, receiving a small amount of money from the Electrical Research Association. Backing came six years later from the National Research and Development Corporation (NRDC), the development of the fuel cell being transferred to Marshalls of Cambridge, where Bacon was appointed Consultant.By 1959, after almost twenty years of individual effort, he was able to demonstrate a 6 kW (8 hp) power unit capable of driving a small truck. Bacon appreciated that when substantial power was required over long periods the hydrogen-oxygen fuel cell associated with high-pressure gas storage would be more compact than conventional secondary batteries.The development of the fuel-cell system pioneered by Bacon was stimulated by a particular need for a compact, lightweight source of power in the United States space programme. Electro-chemical generators using hydrogen-oxygen cells were chosen to provide the main supplies on the Apollo spacecraft for landing on the surface of the moon in 1969. An added advantage of the cells was that they simultaneously provided water. NRDC was largely responsible for the forma-tion of Energy Conversion Ltd, a company that was set up to exploit Bacon's patents and to manufacture fuel cells, and which was supported by British Ropes Ltd, British Petroleum and Guest, Keen \& Nettlefold Ltd at Basingstoke. Bacon was their full-time consultant. In 1971 Energy Conversion's operation was moved to the UK Atomic Energy Research Establishment at Harwell, as Fuel Cells Ltd. Bacon remained with them until he retired in 1973.[br]Principal Honours and DistinctionsOBE 1967. FRS 1972. Royal Society S.G. Brown Medal 1965.

14 Reynolds, Edwin
[br]b. 1831 Mansfield, Connecticut, USAd. 1909 Milwaukee, Wisconsin, USA[br]American contributor to the development of the Corliss valve steam engine, including the "Manhattan" layout.[br]Edwin Reynolds grew up at a time when formal engineering education in America was almost unavailable, but through his genius and his experience working under such masters as G.H. Corliss and William Wright, he developed into one of the best mechanical engineers in the country. When he was Plant Superintendent for the Corliss Steam Engine Company, he built the giant Corliss valve steam engine displayed at the 1876 Centennial Exhibition. In July 1877 he left the Corliss Steam Engine Company to join Edward Allis at his Reliance Works, although he was offered a lower salary. In 1861 Allis had moved his business to the Menomonee Valley, where he had the largest foundry in the area. Immediately on his arrival with Allis, Reynolds began desig-ning and building the "Reliance-Corliss" engine, which becamea symbol of simplicity, economy and reliability. By early 1878 the new engine was so successful that the firm had a six-month backlog of orders. In 1888 he built the first triple-expansion waterworks-pumping engine in the United States for the city of Milwaukee, and in the same year he patented a new design of blowing engine for blast furnaces. He followed this in March 1892 with the first steam engine sets coupled directly to electric generators when Allis-Chalmers contracted to build two Corliss cross-compound engines for the Narragansett Light Company of Providence, Rhode Island. In 1893, one of the impressive attractions at the World's Columbian Exposition in Chicago was the 3,000 hp (2,200 kW) quadruple-expansion Reynolds-Corliss engine designed by Reynolds, who continued to make significant improvements and gained worldwide recognition of his outstanding achievements in engine building.Reynolds was asked to go to New York in 1898 for consultation about some high-horsepower engines for the Manhattan transport system. There, 225 railway locomotives were to be replaced by electric trains, which would be supplied from one generating station producing 60,000 hp (45,000 kW). Reynolds sketched out his ideas for 10,000 hp (7,500 kW) engines while on the train. Because space was limited, he suggested a four-cylinder design with two horizontal-high-pressure cylinders and two vertical, low-pressure ones. One cylinder of each type was placed on each side of the flywheel generator, which with cranks at 135° gave an exceptionally smooth-running compact engine known as the "Manhattan". A further nine similar engines that were superheated and generated three-phase current were supplied in 1902 to the New York Interborough Rapid Transit Company. These were the largest reciprocating steam engines built for use on land, and a few smaller ones with a similar layout were installed in British textile mills.[br]Further ReadingConcise Dictionary of American Biography, 1964, New York: C.Scribner's Sons (contains a brief biography).R.L.Hills, 1989, Power from Steam.

Высота кабельных каналов в свету не ограничивается, но бывает не более 1200 мм. Ширина каналов определяется в зависимости от размеров применяемых кабельных конструкций из условия сохранения прохода не менее 300 мм при глубине канала до 600 мм, 450 мм — от более 600 до 900 мм, 600 мм при более 900 мм.
Полы в каналах выполняют с уклоном не менее 0,5% в сторону водосборников или ливневой канализации.
Для крепления кабельных конструкций в стенах каналов через каждые 0,8—1 м (по длине) устанавливают закладные детали. При заводском изготовлении стеновых панелей детали устанавливают на предприятии-изготовителе. Закладные детали в каналах глубиной до 600 мм располагают в один ряд, при большей глубине каналов — в два ряда.
В местах поворота и разветвления трассы устраивают уширительные камеры, размеры которых выбирают с учетом допускаемого радиуса изгиба прокладываемого кабеля.
